Baltimore bridge collapse: Ship loses power then starts smoking – What CCTV and marine tracking tells us about what happened | World News

Published:

CCTV video and marine tracking data shows the Dali container ship lose power, adjust its course and start smoking before hitting the Baltimore bridge.

The Singapore-flagged container ship left the Port of Baltimore at around 12.45am local time. It’s destination was Colombo in Sri Lanka.

In just over four minutes, the vessel changes course, loses power, starts smoking and hits the Baltimore bridge.

As the Dali approaches the Francis Scott Key Bridge at 1.24:32am local time it appears to lose power for around 60 seconds.

Around the same time, ship tracking data on MarineTraffic shows the Dali alter course as it approaches the bridge.

Just over a minute after appearing to lose power the ship starts producing black smoke.

According to the timings on the CCTV, the ship hits the bridge at 1.28:44am. Four seconds later the bridge collapses.

The evidence appears to tally with a report from ABC News in the US which has cited unclassified intelligence that the container ship lost propulsion as it was leaving port and crew notified officials they had lost control.

‘There should be no room for one-person errors’

A maritime safety expert says the “most likely” cause of the crash was a failure in the ship’s machinery.

David McFarlane, director of Maritime Risk and Safety Consultants Ltd, has told Sky News: “The first thing that springs to my mind is: was there a sudden fault with the ship’s engines or the steering gear? The other, of course, is: was there a navigational error?”

Mr McFarlane says a human error was less likely because of the number of people who would have been on duty.

He adds: “There should be no room for one-person errors because one of the other people should jump in and say ‘hang on…’

“The most likely cause of this is a failure in machinery or steering gear, but we just won’t know until the authorities have been on board. And even then, they’re unlikely to say what’s been going on for some considerable time.”

More than 10 boats help rescue

According to MarineTraffic data, the first ship to arrive around 10 minutes later is a tug Eric Mcallister. It helped the 300-metre container ship leave the port.

It is joined by a second tug Bridget Mcallister and a search and rescue vessel around 25 minutes after the bridge is hit.

More than 10 boats are now involved in the rescue.

Flight tracking data from Flightradar24 shows a police helicopter arriving at 2.04am local time. A coastguard helicopter comes from Atlantic City and arrives at 4.42am.

Vessel involved in separate incident in 2016

The Singapore-flagged ship was previously involved in a minor incident when it hit a quay at the Port of Antwerp in Belgium in 2016, according to maritime accident site Shipwrecklog.
